I have been on the phone with the IRS all morning trying to figure this out. I filed taxes using turbotax as I have the past 4 years. My refund was supposed to be 5834 and instead I got 4677 with the IRS citing an error in filling out the child tax credit portion. The difference is 1157 which is the exact amount of my mortgage interest credit. The people at the IRS were saying that since I got the child tax credit which made my taxes 0 that the mortgage interest credit doesn't apply.

I was told to go to the IRS website and do the "do I qualify for the child tax credit" calculator which asks specifically if you have a mortgage interest credit and their own calculator came up with the same thing turbotax did. Which is right?
